Giyu is a tall young man of a lean muscular stature and pale complexion, who is almost always seen wearing an apathetic expression. He has unruly black hair of uneven lengths that sticks up in tufts around his head, which he wears tied back in a low messy ponytail at the base of his neck. His bangs fall over his eyes in an uneven fringe. His eyes are sharp, moderately large, the irises are deep sapphire that fades to a lighter blue and the pupils a bluish-black, and are framed by thin eyebrows.
